# Create Cluster Groups
Clusters in a namespace can be put into a cluster group. A cluster group is essentially a named selector.
The only parameter for a cluster group is essentially the selector.
When you get to a certain scale cluster groups become a more reasonable way to manage your clusters.
Cluster groups serve the purpose of giving aggregated
status of the deployments and then also a simpler way to manage targets.
A cluster group is created by creating a `ClusterGroup` resource like below
```yaml
kind: ClusterGroup
apiVersion: fleet.cattle.io/v1alpha1
metadata:
name: production-group
namespace: clusters
spec:
# This is the standard metav1.LabelSelector format to match clusters by labels
selector:
matchLabels:
env: prod
```
